The inode allocation failure case in autofs4_dir_symlink() frees the autofs dentry info of the dentry without setting ->d_fsdata to NULL. That could lead to a double free so just get rid of the free and leave it to ->d_release(). Link: http://lkml.kernel.org/r/20160812024759.12352.10653.stgit@pluto.themaw.netSigned-off-by:

The function calls with octal permissions commonly span multiple lines. The current test is line oriented and fails to find some matches. Make the test use the $stat variable instead of the $line variable to span multiple lines. Also add a few functions to the known functions with permissions list. Move the SYMBOLIC_PERMS test to a separate section to find all the S_<FOO> permissions in any form not just those that have specific function names. This can now find and fix permissions uses like: .mode = S_<FOO> | S_<BAR>; Link: http://lkml.kernel.org/r/b51bab60530912aae4ac420119d465c5b206f19f.1475030406.git.joe@perches.comSigned-off-by:Joe Perches <joe@perches.com> Tested-by:

Today there are platforms with many CPUs (up to 4K). Trying to boot only part of the CPUs may result in too long string. For example lets take NPS platform that is part of arch/arc. This platform have SMP system with 256 cores each with 16 HW threads (SMT machine) where HW thread appears as CPU to the kernel. In this example there is total of 4K CPUs. When one tries to boot only part of the HW threads from each core the string representing the map may be long... For example if for sake of performance we decided to boot only first half of HW threads of each core the map will look like: 0-7,16-23,32-39,...,4080-4087 This patch introduce new syntax to accommodate with such use case. I added an optional postfix to a range of CPUs which will choose according to given modulo the desired range of reminders i.e.: <cpus range>:sed_size/group_size For example, above map can be described in new syntax like this: 0-4095:8/16 Note that this patch is backward compatible with current syntax.

The strncpy_from_user() accessor is effectively a copy_from_user() specialised to copy strings, terminating early at a NUL byte if possible. In other respects it is identical, and can be used to copy an arbitrarily large buffer from userspace into the kernel. Conceptually, it exposes a similar attack surface. As with copy_from_user(), we check the destination range when the kernel is built with KASAN, but unlike copy_from_user() we do not check the destination buffer when using HARDENED_USERCOPY. As strncpy_from_user() calls get_user() in a loop, we must call check_object_size() explicitly. This patch adds this instrumentation to strncpy_from_user(), per the same rationale as with the regular copy_from_user(). In the absence of hardened usercopy this will have no impact as the instrumentation expands to an empty static inline function.

There are four cases I can see where we could end up with a NULL 'slot' in radix_tree_next_slot(). This unit test exercises all four of them, making sure that if in the future we have an unsafe path through radix_tree_next_slot(), we'll catch it. Here are details on the four cases: 1) radix_tree_iter_retry() via a non-tagged iteration like radix_tree_for_each_slot(). In this case we currently aren't seeing a bug because radix_tree_iter_retry() sets iter->next_index = iter->index; which means that in in the else case in radix_tree_next_slot(), 'count' is zero, so we skip over the while() loop and effectively just return NULL without ever dereferencing 'slot'. 2) radix_tree_iter_retry() via tagged iteration like radix_tree_for_each_tagged(). This case was giving us NULL pointer dereferences in testing, and was fixed with this commit: commit 3cb9185c ("radix-tree: fix radix_tree_iter_retry() for tagged iterators.") This fix doesn't explicitly check for 'slot' being NULL, though, it works around the NULL pointer dereference by instead zeroing iter->tags in radix_tree_iter_retry(), which makes us bail out of the if() case in radix_tree_next_slot() before we dereference 'slot'. 3) radix_tree_iter_next() via via a non-tagged iteration like radix_tree_for_each_slot(). This currently happens in shmem_tag_pins() and shmem_partial_swap_usage(). As with non-tagged iteration, 'count' in the else case of radix_tree_next_slot() is zero, so we skip over the while() loop and effectively just return NULL without ever dereferencing 'slot'. 4) radix_tree_iter_next() via tagged iteration like radix_tree_for_each_tagged(). This happens in shmem_wait_for_pins(). radix_tree_iter_next() zeros out iter->tags, so we end up exiting radix_tree_next_slot() here: if (flags & RADIX_TREE_ITER_TAGGED) { void *canon = slot; iter->tags >>= 1; if (unlikely(!iter->tags)) return NULL; Link: http://lkml.kernel.org/r/20160815194237.25967-3-ross.zwisler@linux.intel.comSigned-off-by: -

There are four cases I can see where we could end up with a NULL 'slot' in radix_tree_next_slot(). Yet radix_tree_next_slot() never actually checks whether 'slot' is NULL. It just happens that for the cases where 'slot' is NULL, some other combination of factors prevents us from dereferencing it. It would be very easy for someone to unwittingly change one of these factors without realizing that we are implicitly depending on it to save us from a NULL pointer dereference. Add a comment documenting the things that allow 'slot' to be safely passed as NULL to radix_tree_next_slot(). Here are details on the four cases: 1) radix_tree_iter_retry() via a non-tagged iteration like radix_tree_for_each_slot().

The select(2) syscall performs a kmalloc(size, GFP_KERNEL) where size grows with the number of fds passed. We had a customer report page allocation failures of order-4 for this allocation. This is a costly order, so it might easily fail, as the VM expects such allocation to have a lower-order fallback. Such trivial fallback is vmalloc(), as the memory doesn't have to be physically contiguous and the allocation is temporary for the duration of the syscall only. There were some concerns, whether this would have negative impact on the system by exposing vmalloc() to userspace. Although an excessive use of vmalloc can cause some system wide performance issues - TLB flushes etc. - a large order allocation is not for free either and an excessive reclaim/compaction can have a similar effect. Also note that the size is effectively limited by RLIMIT_NOFILE which defaults to 1024 on the systems I checked. That means the bitmaps will fit well within single page and thus the vmalloc() fallback could be only excercised for processes where root allows a higher limit. Note that the poll(2) syscall seems to use a linked list of order-0 pages, so it doesn't need this kind of fallback.

After much discussion, it seems that the fallocate feature flag FALLOC_FL_ZERO_RANGE maps nicely to SCSI WRITE SAME; and the feature FALLOC_FL_PUNCH_HOLE maps nicely to the devices that have been whitelisted for zeroing SCSI UNMAP. Punch still requires that FALLOC_FL_KEEP_SIZE is set. A length that goes past the end of the device will be clamped to the device size if KEEP_SIZE is set; or will return -EINVAL if not. Both start and length must be aligned to the device's logical block size. Since the semantics of fallocate are fairly well established already, wire up the two pieces. The other fallocate variants (collapse range, insert range, and allocate blocks) are not supported.

Darrick J. Wong authored
Patch series "fallocate for block devices", v11. This is a patchset to fix page cache coherency with BLKZEROOUT and implement fallocate for block devices. The first patch is a fix to the existing BLKZEROOUT ioctl to invalidate the page cache if the zeroing command to the underlying device succeeds. Without this patch we still have the pagecache coherence bug that's been in the kernel forever. The second patch changes the internal block device functions to reject attempts to discard or zeroout that are not aligned to the logical block size. Previously, we only checked that the start/len parameters were 512-byte aligned, which caused kernel BUG_ONs for unaligned IOs to 4k-LBA devices. The third patch creates an fallocate handler for block devices, wires up the FALLOC_FL_PUNCH_HOLE flag to zeroing-discard, and connects FALLOC_FL_ZERO_RANGE to write-same so that we can have a consistent fallocate interface between files and block devices. It also allows the combination of PUNCH_HOLE and NO_HIDE_STALE to invoke non-zeroing discard. Test cases for the new block device fallocate are now in xfstests as generic/349-351. This patch (of 3): Invalidate the page cache (as a regular O_DIRECT write would do) to avoid returning stale cache contents at a later time.

Upper layers (e.g., UBI) should make use of these in the near future" * tag 'for-linus-20161008' of git://git.infradead.org/linux-mtd: (35 commits) mtd: nand: fix trivial spelling error mtdpart: Propagate _get/put_device() mtd: nand: Provide nand_cleanup() function to free NAND related resources mtd: Kill the OF_MTD Kconfig option mtd: nand: mxc: Test CONFIG_OF instead of CONFIG_OF_MTD mtd: nand: Fix nand_command_lp() for 8bits opcodes mtd: nand: sunxi: Support ECC maximization mtd: nand: Support maximizing ECC when using software BCH mtd: nand: Add an option to maximize the ECC strength mtd: nand: mxc: Add timing setup for v2 controllers mtd: nand: mxc: implement onfi get/set features mtd: nand: sunxi: switch from manual to automated timing config mtd: nand: automate NAND timings selection mtd: nand: Expose data interface for ONFI mode 0 mtd: nand: Add function to convert ONFI mode to data_interface mtd: nand: convert ONFI mode into data interface mtd: nand: Introduce nand_data_interface mtd: nand: Create a NAND reset function mtd: nand: remove unnecessary 'extern' from function declarations MAINTAINERS: Add maintainer entry for Ingenic JZ4780 NAND driver ... -
